氨酯的制备

Making Anunoniaester

由2-氨基磺酰基-N,N-二甲基烟酰胺(简称“磺酰胺”)为原料,用热法代替冷法制备烟嘧磺隆的直接中间体2-乙氧基羰基氨基磺酰基-N,N-二甲基烟酰胺(简称“氨酯”)得到较满意的结果。

Using 2-aminosulfonyl N,N-dimethyl niaciamide (Abbreviation:sulfamide)as material, Thermal-process replace cold-process and making 2-oxethylcarboxideamino sulfonyl-N, N-dimetylniaciamide(abbreviation:ammoniaester), The belowings are summarized
